(Left panel) The centrality dependence of $\Delta\gamma_{1,1}/v_2$ and $\Delta\gamma_{1,2}/v_3$ for Pb--Pb collisions at $\sqrt{s_\mathrm{{\rm NN}}} = 2.76$~TeV according to the AMPT and BW-LCC model. (Right panel) The differences between $\Delta\gamma_{1,1}/v_2$ and $\Delta\gamma_{1,2}/v_3$ in AMPT and BW-LCC, denoted as $\Delta(\Delta\gamma/v_{\mathrm{n}})$ The solid and dotted line is the result of a fit with a constant function to AMPT and BW-LCC result respectively.
